When water freezes it expands. This process creates pressure inside of the rock, which causes it to burst open from the inside.
Water from frost or rain gets between cracks on a rock. At night this water freezing and expands. The expansion of the water in the cracks causes the rock to break little by little. This cycle is repeated many times.
in cold countries,water freezes inside cracks of rocks,expands,and causes rocks to break.
The water can get inside and then freeze which in turn cracks the rocks open.
Water has the unusal property of expanding, when frozen into ice. Water that seeps into cracks and then freezes, exerts tremendous pressure, which forces the crack open. During a thaw the loose parts will fall out.
Water and freezing/cold weather can make rocks break. The water makes the rocks break when it goes into the rock cracks. When the weather gets cold/freezing the water expands and the rock breaks. Or with a really good hammer. LOL:P
When water in little fractures or cracks in a rock freezes, and since water expands when it freezes, it causes the crack to enlarge a little bit. The cycle of this happening over and over until the cracks are big enough to split the rock apart is Frost Wedging.
Water goes into small cracks in the rocks and then freezes. Water expands as it freezes and the expansion pushes outwards on the crack in the rock making it bigger. Eventually this process causes the rock to crack and flake apart
because freezing causes brittleness, it would break.
Erosion is the main force that acts on rocks to break them down into sand. Water getting into cracks, freezing and expanding also helps to break down rocks.
Rocks are already frozen (unless it is molten lava). Otherwise mountains would simply be piles of dust. Water freezing in cracks or variations in the rock can cause breaking.
Temperatures such as freezing and thawing water causes the rock to split. Also, if something causes it to shift position and fall on another rock, it may break up.
twist it until it cracks
